Answer 1

Step-by-step explanation:

we need to find the slope of each line.

the slope is the ratio y/x indicating how many units y changes, when x changes a certain amount of units.

parallel lines have the same slope.

for a perpendicular line x and y in the slope ratio are put upside down, and the sign is flipped (+ to - and vice versa).

a.

2x - 8y = -24

2x + 24 = 8y

y = 2/8 x + 24/8 = 1/4 x + 3

the slope is 1/4 (always the factor of x).

4x + y = -2

y = -4x - 2

the slope is -4 = -4/1.

this line is therefore perpendicular to the first line.

x - 4y = 4

x - 4 = 4y

y = 1/4 x - 4/4 = 1/4 x - 1

the slope is 1/4.

this line is therefore parallel to the first line.

b.

3x - 9y = 9

9y = 3x - 9

y = 3/9 x - 9/9 = 1/3 x - 1

the slope is 1/3

3y = x + 12

y = 1/3 x + 4

the slope is 1/3.

this line is therefore parallel to the first line.

2x - 6y = 12

6y = 2x - 12

y = 2/6 x - 12/6 = 1/3 x - 2

the slope is 1/3.

this line is therefore parallel to the first line.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The figure is dilated by a a scale factor of 2.5.

Now, We know that;

After dilation we get the pre image of the image which orientation of the figure is not change and both are similar to each other.

Mr James gives £500 to his children Ally,
Barry and Cat in the ratio 2:3:5.
How much do they each receive?

Answers

Answers:

Ally gets 100 poundsBarry gets 150 poundsCat gets 250 pounds

=====================================================

Work Shown:

x = some positive real number

2x = amount Ally gets

3x = amount Barry gets

5x = amount Cat gets

Note that the ratio 2x:3x:5x reduces to 2:3:5 after dividing all parts by x.

Add up the parts and you should get a sum of 500 pounds. Solve for x.

2x+3x+5x = 500

10x = 500

x = 500/10

x = 50

Based on that x value, we then can say:

2x = 2*50 = 100 pounds is what Ally gets3x = 3*50 = 150 pounds is what Barry gets5x = 5*50 = 250 pounds is what Cat gets

As a check, 100+150+250 = 500.

Also, note that the ratio 100:150:250 fully reduces to 2:3:5 after dividing all parts by the GCF 50.

Those two facts help confirm our answers.

Let (x1, y1) = (10, 30)
(x2, y2) = (50, 50)

Use the following slope formula:

m = (y2 - y1)/(x2 - x1)
m = (50 - 30) / (50 - 10)
m = 20/40 or 1/2

Therefore, the slope of the line is 1/2.

Answers

Answer:

I'm guessing frequency means deposits,

a. 13

b. $50

c. not sure what this means (sorry!)

d. $2,535

Step-by-step explanation:

Can I have brainliest? It would help me out, if not thanks anyways! Hope this helped and have a nice day!

Part A

Answer: 13

-------------

Explanation:

Add up all the values in the frequency column. This is because everything in the table represents a deposit of some kind.

3+1+5+2+2 = 13

========================================================

Part B

Answer:  $50

-------------

Explanation:

Simply list the value that has the highest frequency. This is the mode. It's possible to have more than one mode, and it's also possible to not have any mode at all.

========================================================

Part C

Answer:  Median

-------------

Explanation:

Let's list out all of the deposits. The repeats aren't typos. The deposits are

125, 125, 125, 300, 50, 50, 50, 50, 50, 205, 205, 100, 100

They sort to

50, 50, 50, 50, 50, 100, 100, 125, 125, 125, 205, 205, 300

Since we have n = 13 items here, the halfway point is n/2 = 13/2 = 6.5 which rounds to 7. The median is in slot 7. We have 6 items below the median and 6 items above the median (giving 6+1+6 = 13 total).

The value in slot 7 is 100, which shows us that 100 is the median.

========================================================

Part D

Answer:  $2535

-------------

Explanation:

Form a third column of values where we multiply each deposit by the corresponding frequency. Check out the table below.

After this third column is formed, add up those values to get the total amount of deposits. Spreadsheet software can make quick work of something like this. I used OpenOffice spreadsheet which is free software.

You should find that 1535 is the total amount deposited. This value is then added onto the $1000 already in there to get 1000+1535 = 2535
